Dashboard links broken when inside folder

I have a Dashboard view inside a folder with code coverage portlet. Job URLs in that portlet are broken as they use domain relative URLs without leading '/' like 'job/Folder/view/Result/job/Folder/job/my_job/42/' while i should be '/job/Folder/job/my_job/42/' (or '/job/Folder/view/Result/job/my_job/42/').

On first sight it seems fixable removing href attribute.

<t:buildLink jobName="${r.parent.name}" job="${r.parent}" number="${r.number}" href="${r.url}" />
